Thudding sound when braking the car to bring it to a complete stop. I bought the car in 1998, changed the front disc brakes and had the rotor machined at an authorized Toyota dealer in Gilroy, CA in 2002. Thudding noise began 2 weeks after the brake pads were replaced. The Toyota dealer's inspection could not detect the thudding sound so the dealer certified the brakes as ok. When I drive the car home I find that on a quiet road the thudding sound is audible when braking to a halt.
Poor quality on key components like brakes on 1998 Toyota Camry.
I own a 1998 Camry as well and have suffered similar brake problems. I eventually had the problem rectified by Canadian Tire (beleive it or not). There generic brake parts actually fixed the annoying multiple visits to Toyota dealers with no progress.
Check your brake calipers.
Don't be misguided by this opinion. Sure mine is just an opinion also, but my Camry has almost 240,000 miles on it and I have not had 1 single problem with it.
So do you advise to not check his brakes?
